Feature Request - Bigger Fonts

[PetrusVermaak]

As we get older smaller text is becoming harder to read.

Can we include a bigger font option in the spanner icon so people can increase it when they need it. Instead of just giving two sizes allow user to increase themselves with numerical value?

For many of us older folk, the biggest setting on the 'aA' is still too small. I have so many people asking for this.

Just to clarify, this function needs to translate to the online reader as well please.

I know you guys might not use it, but we use this extensively when running a course with students,
